The Quintessential Quintuplets Newest Sister

“Bye Nino, have fun with supplemental classes,” Yotsuba said mocking her.

“Don’t bother Futaro too much,” Ichika said to her.

“We’ll be thinking of you both,” Miku said to the.

“Just because we’re going to be gone for the next few weeks that doesn’t mean that you get to try anything with Futaro,” Itsuki said.

“Haah? Do you really think that I want to spend the entire summer with just him!?” Nino said to them.

“You girls earned this,” Futaro said to them. “Go have fun but remember to get in a bit of studying whenever you can. While you all may have passed there are still a lot of improvements that can be made.”

“Don’t be stuck a stick in the mud Futaro,” Itsuki said, as the four girls made their way out. “Remember to have some fun yourselves.”

Once the girls left Futaro was finally alone to deal with Nino.

“This isn’t fair,” she said to herself. “Why I am the only one that has to stay home all summer. They get to spend the whole summer with father, while I’m stuck here studying.”

“If you have time to feel sorry for yourself, you have time to study,” Futaro said sitting her down on the couch. “Look at these and tell me what you see,” he said placing her test scores onto the table.

“They’re my test’s so what,” she said, trying to avoid looking at them.

“10 points in Mathematics, 13 in Literature, 5 in History! And don’t even get me started on the rest of them,” he said to her, angry enough to blow a blood vessel. “Did you even try to study or were you busy goofing off again?”

“I tried my best,” she said embarrassed by how close he got to her face while yelling at her.

“Yeah, you tried your best alright, your best at failing! Even Yotsuba did better than you this time around. What the heck were you even doing?”

“I said that I did my best!” she said yelling back at him.

“Well, your best wasn’t good enough,” he said pointing to her test scores. “From now on I’m going to develop a strict study schedule for you to follow. I will eventually have to change it for when you go to supplemental classes, but for now, what matters is that I do my best to make sure that you are studying your hardest.”

“Haah?! You can’t expect me to waste my whole summer studying now can you?” Nino said back to him annoyed.

“Of course, I do, now savor these last moments of freedom because You’ll be studying non-stop for the rest of the summer.”

Nino groaned to show that she wasn’t happy with this, but Futaro didn’t care. After that, it only took him a few hours to create the perfect study plan for Nino. Since she was the only one that he had to deal with right now he could put everything that he had into it.

For the next several days Futaro made Nino study non-stop. Over and over, he would have her copy down the same notes, to make sure that they would be ingrained into her mind. Then he made her practice over and over again with basically the same questions, but he formatted them to be worded differently every time. He would make sure that Nino would be more than ready by the time her supplemental classes started.

While Futaro thought everything was going great Nino on the other hand did not. Thanks to his strict tutoring she barely had enough time in the morning to do her daily beauty routine. It was starting to annoy her, and she was just about to snap at him.

“You call this any better?” he said showing her that she got a 7 on her practice test. “You can do better! I know you can! Come on try harder!”

‘“Just shut up already!” Nino yelled at him, turning away to show he couldn’t see her start to cry. She had been trying her very best to study, but Futaro didn’t understand that his current method if teaching her wasn’t helping, in fact, it was making things worse.

“Are you seriously going to complain?” Futaro said, not understanding the situation at all. “You can complain all you want but that doesn’t help your current test scores out at all.”

“Haah?! It’s not like I did that bad or anything idiot! I’m trying my best!” Nino yelled running out of her home before Futaro could stop her. She needed some time away from him, some time to relax.

The best place that she knew that she could get away to without Futaro immediately finding her was the old shrine near her home. It was already night, but the air was still warm. Nino especially loved the summer because it was the time when she could be herself, or at least she thought.

Futaro didn’t understand her at all. It’s not like she wanted to have a hard time studying, it was just that Futaro never cared to teach her the right way. When it came to her sisters, she could tell that she ranked lowest among them in his eyes. Her test scores proved it. If only Futaro could understand what she was going through perhaps things could be different between them.

When Nino finally made her way to the shrine she sat down on top of the steps and listened to the crickets. It was here that she could finally relax.

“Oh my, what is a pretty thing like yourself doing here all by your lonesome?” An old lady Miko said, slowly making her way to Nino.

“Here let me help,” Nino said, helping the old lady to a bench where she could sit down.

“Thank you, dear, you’re such a kind young lady,” the old woman said to Nino.

“You’re wrong I’m a bad girl,” Nino said sitting down to the old lady.

“And why is that?” she asked curious why a pretty girl before her was depressed.

“I keep letting everyone down,” Nino said, just letting all of her emotions out. “I try and try, but in the end, it doesn’t matter. My whole family gets to go on vacation while I’m stuck home with my tutor. I’m trying to learn, but the more he explains something and the more he makes me cram something into my head the less I know.”

“Hmm, have you tried talking to him about this?” the old lady asked.

“I try to, but whenever I’m near him I get all flustered and can’t manage to say the right things. I just had an agreement with him because of that. I just wish that he would understand what I’m going through.”

“Ah, to be young,” the old lady said, realizing that this girl was in love with this young man, but was too shy to express her true emotions.

“You know I wasn’t very good at studying myself. I was always causing problems for my family, but they never gave up on me. I can’t say that I did anything grand in my long life, but I am living one that I’m happy with. The important thing is that you never give up on yourself.”

“That’s easy for you to say,” Nino said to her. “If only Futaro would understand how I feel, things could start to change.”

“Well, if that’s all you’re looking for then I do believe that you have come o the right place,” the old lady said, slowly standing up. “Wait right here,” she said, making her way into the nearest building. A few minutes later the old lady returned carrying what looked like a shrine charm in her hands.

“This is all you need to make that special someone of yours know exactly how you feel,” she said holding out the charm.  “I promise that he will be better at understanding you. All you have to do is wish for it.”

“Are you sure that this will work?” Nino asked skeptically about a simple shrine charm that could grant her wish.

“I’m certain that it will work, or your money back guaranteed.,” the old lady said to her with a big smile on her face.

“Wait, I have to pay for this?” Nino said. “I thought that you were going to give it to me as a gift.”

“Now young lady gifts are nice and all, but they don’t help keep this shrine in one peace. Only money can do that.”

“Fine,” Nino said, pulling out her wallet. “How much is it, 500 yen?”

“5000 yen,” the old lady said to her with a smile on her face.

“5000! That’s insane!” Nino yelled in protest. “I don’t even need that stupid thing!”

“Well, if you don’t want it I guess that I’ll just burn it,” the old lady said, pulling out a lighter. She started a flame and slowly brought the shrine charm closer to it.

“Wait don’t!” Nino yelled, stopping the old lady from bringing the flame any closer. “I’ll buy alright,” she said holing out the money.

“That’s better,” the old lady said, handing Nino the charm as she took the money from her hands. “It’s always best when you're true to yourself, but I don’t think that I hate your shy side, it’s cute. Perhaps that boy will learn to like it as well.

The old lady then started walking back towards the shrine, leaving Nino alone with her new charm.

“Ugh this is ridiculous,” Nino said, looking at the charm. “How could I fall for that old lady's trick. I was definitely conned. Though I guess it couldn’t hurt to try now could it?” Nino gripped the charm in her hands as she made her wish.

“I wish that Futaro could understand me. I wish he could know my pain. I wish I could have all of his intelligence and that annoying confidence of his. I want him to understand what it means to be me.”

After seconds of waiting nothing happened to Nino’s disappointment. “I guess it really was a scam,” she said shoving the charm into her pocket.

“Nino there you are!” Futaro yelled making his way over to her. “I’ve been searching everywhere for you. Why did you go running off like that?”

“If I have to tell you then you don’t deserve to know,” she said walking away from him. “Let’s go home, I’m tired and I want to sleep.”

“Fine, I’ll let you off for today because you seem stressed, but tomorrow we’ll go right back to studying,” Futaro said following after her.

Futaro may be book smart. But when it came to the matters of a girl's heart he was as dumb as they come. Nino didn’t talk to Futaro for the rest of the night and when they returned home she immediately went to her room.

“Ekkkkkkkkkk! Nino what did you do!” Futaro yelled at the top of his lungs upon looking at his reflection through the bathroom mirror.

“What’s wrong?!” Nino yelled running to the bathroom.

“Pfft! Hahhahahahah!” Nino began to laugh at Futaro relentlessly seeing that his hair was now the same color pink as her own. “That’s a, pfft, good look for you,” she said trying to hold back her laughter.

“Nino! I know that it was you who did this so fess up!” Futaro yelled at her.

“I have no idea what you’re talking about,” Nino said back to him.

“Fine if you want to be that way and lie to me get ready for an extra hard study session today. Come with me!” he yelled grabbing her arm and dragging her to the living room where the study materials were still left out from last night.

“First thing’s first, take this examine,” he said giving her a mock test that he knew that she wasn’t ready for. “If you had time to dye my hair while I slept then you had the time to study.”

“Haah?! Don’t blame me for this. This is obviously you trying to copy my cute hair color!” Nino yelled back at him, ripping the mock test out of his hands. “But fine I’ll play your game and I will win!”

Nino sat down and started to take the test. Though to her surprise, she wasn’t as confused as she thought she’d be. While she didn’t know how to answer all of the questions she did her best to show as much work as possible. She’s never been this invested in a test before, and truth be told it was actually a bit fun.

“Done!” she said standing up and then handing Futaro the paper.

“Are you sure?” Futaro asked her. “There’s still ten minutes left, don’t you want to check your work one last time?”

“Nope, don’t need to,” she said proudly of herself. For the first time in a whole, she actually felt like she did a good job.

“Fine suit yourself,” Futaro said looking over her answers. “Haah?! How is this possible?!” Futaro yelled out in shock.

“What’s wrong did I fail again,” Nino asked looking somewhat depressed.

“No it’s the exact opposite,” Futaro said handing back her test to her. “You passed with a 42. I can’t believe it.”

“Yes!!!” Nino jumped up and down in joy. This was the first time that she had ever scored this high before. “And you thought that I couldn’t do it,” she said mocking Futaro who was just standing there in shock.

“This should be impossible,” he said to her. “I never made you study anything that was on that test. You should have not passed.”

“Ohoho, it looks like when Futaro tried to sabotage me he accidentally realized my inner genius!” Nino said mocking him some more.

“Be honest after you dyed my hair you looked around and copied the answer key to this test,” Futaro said to her, doubting her score.

“Haah?! You’re just jealous that I didn’t need your help for this test!” Nino yelled at him. While she didn’t know how she got such a high score that didn’t mean that she cheated.

“How about I take out some random test and have you take it?” she said challenging him. “You think that you’re so smart, but that’s wrong! If you didn’t know what was going to be on the test you would get the same scores as me.”

“Fine, I’ll show you what actual effort looks like,” Futaro smugly sat down waiting for Nino to hand him a test.

“Here try this one,” Nino said taking out a random test from the stack of mock tests that Futaro had laid out for her.

“Child’s play,” he said, upon seeing the first question. For him, this test was going to be a breeze, an easy 100.

After a half-hour passed Futaro set his pencil down and handed it to Nino to check it with the answer seat. He didn’t bother going over his answers since he knew that he got everything right.

“Hmm, so if this is this, and that is that,” Nino mumbled to herself checking his answers. “Futaro scored an 89,” Nino said handing Futaro back the test.

“I’m sorry, but this can’t be right,” Futaro said to her shocked that he didn’t get a hundred. “You messed upgrading it, I knew that I should have done it myself,” he said taking the answer sheet from her hands.

“See right here,” Futaro said grabbing her attention. The answer sheet says that my answer is right.”

“Um Futaro, that isn’t what you put she said pointing to his test answer. “You misspelled it right here. I had to mark it as a failure due to the guidelines of the answer sheet.

“Haah?!” No way!” Futaro yelled out in shock. “How could I make such a simple mistake!”

“Oh, and it’s not just one either,” Nino said to Futaro, trying to rub some more salt into his wounded pride. “For each question that you got wrong, it was all due to simple spelling errors. I guess even the great Futaro isn’t great at everything,” she said mocking him. “If you want, I could help you out sometime, because spelling is what I excel at.”

“I was just going easy on you!” Futaro yelled at her. “It’s not like I made those spelling mistakes by accident. Just be glad that I didn’t get a 100 or your score would have looked far worse!”

“Whatever you say,” Nino said, smiling back at him. She was actually enjoying seeing Futaro act all shy like this. He was actually kind of cute. Perhaps that charm did have a little magic in it.

“You wait right here!” Futaro yelled at her. “I’ll be back with a test you’re sure to fail!” Futaro brought out a mock test that he was intending to use for himself, but if Nino wanted to be smug about making a fool of him, she would have to pay for it.

“Try this one out for size,” he said handing her the mock test. “If you can’t get above a 30 on this then your still no match for me,” he said to her confidently, not understanding why he even started such a competition with her.

“Fine, I’ll prove to you that I’m not as dumb as you think I am,” she said starting the test. Once again this test didn’t feel that hard in fact she felt like she knew more of the answers on this one than on the last one.

“And done,” she said handing the mock test to Futaro. He began to go over his questions and as he did she watched his face slowly go into shock.

“Haah?! How is this possible?!” he yelled in frustration. “You got a 48 this time! It’s higher than your previous score! This shouldn’t be possible!”

“I guess that Futaro wasn’t able to see my true talent after all,” she said skipping away to her room. “Since I did so well, let’s call it quits for today. I wouldn’t want to hurt your pride more so than it already is,” she said, mocking him as she closed her door.

“OMG! I can’t believe that just happened!” she yelled to her in joy. This was the first time that she did so well on tests. She guessed that talking to that old lady last night was worth it.

“How the hell did this happen?” Futaro asked himself, reviewing the two mock tests that Nino took. There were noticeable answers in her work, but in the end, she came to the right answer. The Nino he knew could have never gotten such scores. She must have done something to cheat that was the only logical explanation.

The next day Futaro changed again. His hair was a bit longer and it appeared that he had shrunk by an inch. His face even appeared to be more delicate, than before.

“Nino, did you get taller overnight?” Futaro asked her, clearly unaware that he had shrunk. Though unlike him, Nino noticed the changes in his body almost instantly, and it was then that she remembered that exact wording of her wish.

“I wish that Futaro could understand me. I wish he could know my pain. I wish I could have all of his intelligence and that annoying confidence of his. I want him to understand what it means to be me.”

She was taking his intelligence from him and he was slowly turning into her. This explains why she was able to get such high scores yesterday and why he was having several spelling errors in his work.

She also found Futaro’s current appearance quite cute, perhaps in a few more days, he’ll look just like her. Now that she knew what was happening she was going to pay back Futaro for everything he made her go through.

”Hey Futaro for today's study session could you go over a few things with me. I’m having a hard time understanding everything,” she said wanting to test her theory. If Futaro was slowly trading intelligence with her she wanted to see him clumsily try to explain an answer to her.

“I don’t know how you were able to get such high scores yesterday, but if it means that you're becoming more dedicated to studying then I’m all in,” he said, sitting down at the table. “Show me what you having problems with.”

“Right here,” she said showing him a question that she herself knew that answer to, but wanted to see if he knew it as well.”

“Oh this is an easy question,” he said to her without taking his eyes off the paper, not noticing that she wasn’t looking at the paper, but at him.

“All you have to do to solve this question is to, uh, what I mean to say is that to answer this question you have to, uh. No that’s not right. What about this?” he said to himself, starting to feel frustrated that he was having difficulties with this question which he could normally solve in his sleep.

“Wait Futaro,” Nino said, casually taking the pencil from his hands. “Don’t we have to do this,” she said solving the question without his help.

“That’s correct,” he said to her with an astonished look on his face.” I knew that you could do it. Why else would I purposely pretend to have problems with such an easy question.,” he said to her trying to bluff his way out of this. He was so embarrassed right now but refused to show it. He had to remain the cool and collected tutor at all times. Though that being said, he was by no means cool and collected yesterday.

“Thank you Futaro,” Nino said already understanding what he was trying to do, but she was no longer the quick to anger tsundere Nino, she was slowly becoming the genius, Nino! Soon Futaro will be the one that needs her help to answer questions!

As the days slowly passed Nino’s intelligence rose to Futaro’s shock. For a girl who just several days prior had problems answering a simple question, this was unheard of. On her current mock test, she scored a 65!

At the same time, Futaro’s appearance started to change to a more noticeable degree. His hair was now as long as Nino’s, and while he was still taller than her he had definitely shrunk to a shocking degree. He started to feel weird as his gut was starting to shrink, while his ass, thighs, and chest were getting fatter.

Concerned by these changes he tried to cut his hair in the morning so that Nino would notice and he made sure that he wore extra baggage clothes. Though unfortunately for him Nino already could tell that he was progressing along smoothly.

Though what concerned Futaro the most were his own test scores. While Nino took her own mock tests, Futaro did the same. He wanted to make sure that he was always on top of his game. Though to his dismay, he saw a significant change in his own scores. He never showed them to Nino, but on his recent mock test, he scored a 57!

This was a mock test that he took a few weeks ago and managed to get a 100 on. To score such a low score for him was impossible. He tried to figure out what was going on, but it was no use. He tried changing his study tactics, his sleep schedule, and what he ate while he studied, but none of it worked. Something was clearly wrong with him, but his foolish pride wouldn’t allow him to admit it.

The next day Futaro’s pride took a serious blow when Nino came up to him while he was having a hard time answering a question. She had already finished all of the study material given to her for the day and wanted to check on Futaro’s condition. Today his face looked almost like an exact replica of her own.

“What do you want Nino?” Futaro asked her while focusing on the question. Can’t you see that I’m busy, go back to your study material, I'm sure that you’re not done with it yet,” he said trying to wave her away, but instead she decided to move closer to him.

“Futaro, you’re doing this all wrong,” she said pointing out several errors that he made. “Here let me show you,” she said, as she calmly explained the best way for him to solve the question and how to recognize when to use this method.

Futaro was shocked. Unlike himself who was a very direct and harsh tutor, Nino was kind and gentle. He could no longer see her as the Nino that he knew.

“Oh my, is Futaro alright?” Nino asked in a condescending tone. I thought that a problem like this was easy for you,” she said mocking him. “To think that you needed my help, of all people my help. I guess even the great Futaro can have an off day or several,” she said, making her way out of Futaro’s room snickering to herself.

“Argh!” Futaro yelled in frustration, throwing everything that was on his desk to the ground. How dare she make fun of him like this! How dare she treat him like an idiot! How dare she help him! How dare she make his heart start to beat for her attention.

Futaro soon went to sleep after that, but he couldn’t stop thinking about what he had just felt. He almost felt good being helped by Nino.

When woke up the next morning to his surprise Nino was already there. “About time you woke up lazy butt,” she said pointing to his alarm clock which said that it was 1 pm in the afternoon!

“What the hec-” Futaro instantly covered his mouth when he noticed that his voice had turned high-pitched like Nino’s. Then to his second shock, he just remembered that he liked sleeping with his shirt off and now Nino had a direct view of his chest!

“Ekkkkk! Don’t look!” Futaro screamed like a girl, trying his best to cover his chest which he had just noticed started to look more and more like breasts to him.

“It’s alright Futaro,” Nino said hugging him. “I promise that we’ll find a way to fix this,” she said lying to him. Why the hell would she want to fix this? This was even better than she thought. “Though for now, we should keep this a secret for now.”

“Alright,” Futaro said, complying with her. He didn’t know if it was do to the mental stress he was under or something else, but Nino seemed very reliable to him at the moment.

“Though before we do anything we should get you situated first,” she said to him with a smile across her face. “Wait right here she said. A few minutes later Nino came in with a bunch of her clothes in her arms.

“Um, Nino what’s this?” Futaro asked her, concerned by what she was planning.

“They are your new clothes,” Nino said, dropping most of the clothes onto his bed. She held up a pair of white panties and a white bra.

“Nino what are you doing?! Let go!” Futaro yelled as she pulled away from his blanket before handing him his new underwear.

“Futaro, I want to help you, but I can’t help you if you won’t let me.  Since for some reason your body is being shaped into mine, I refuse to let you treat it like you usually do. Now put on those panties and I’ll help you with the bra.”

For some reason, Futaro couldn’t help but obey Nino. It’s as if he wanted to make her happy. Perhaps if he wasn’t shocked by today’s sudden change, he would have protested a bit more.

“There you go,” Nino said happily watching him slowly and embarrassingly pull the panties up his legs. When they were finally on she saw his small little bugle popping out. It would seem that the transformation had already started to affect more of his manhood than he thought.

“Okay little lady let’s get this bra on you,” she said walking around him. “You see to put a bra on all you have to do is this,” she said slipping the bra over his chest. “Now for the first few days, I’ll be helping you put this on. Don’t worry it’s tough for all girls at first.”

“I’m not a girl,” Futaro said to her, embarrassed that he was now wearing a bra thanks to Nino.

“Are you sure, because that is all I can see right now,” she said to him directing him to his full body mirror in nothing else but his underwear. “Just look and tell me what you see.”

“Do you see a boy, or do you see a girl?” she asked him.

“I see a man,” Futaro tried his best to not stare so much at his new form.

“Are you sure about that?” she asked as she slowly started to caress Futaro’s body. “Do boys have breasts as short as yours, or skin that is smooth as silk. Do they have delicate faces and a thicc ass like yours? What about that package of yours? I don’t think that there are that many boys out there with a package as small as yours.”

“You don’t know what you are talking about,” Futaro said back to her. “I’m a man!”

“Yes, so says the person that is afraid of their own reflection,” Nino said mocking him.

“I’m not afraid!” Futaro yelled at her, turning to face the mirror. Though when he did he was shocked to see that he actually looked quite cute. His face started to blush as he got lost for a second by just looking at his own reflection.

“See what I told you, there’s no way that you’re a boy,” Nino said, whispering into Futaro’s ear.

“Haah?! It’s not like I think that I’m cute or anything idiot!” Futaro yelled at her trying to hide his embarrassment.

“Aww, is the cute little sissy shy about how cute they look?” Nino asked, mocking Futaro.

“Shut up! I’m not cute and I’m not a sissy!” Futaro yelled at her.

“Alright there is no need to yell,” Nino said, realizing that if she went any further there could be problems for her. “Now, let’s get you dressed, or do you want t begin our study session today in nothing but my underwear.”

“Wait this is yours!” Futaro yelled in shock. He had to take these off now. If her father, Futaro’s employer found out about this his life would be over.

“Don’t worry about it,” Nino said, ignoring his panicking, leading him over to his bed so that she could pick him out some cute to wear. “Here try this on,” she said handing him her school uniform.

“What?! I’m not wearing this,” he said trying to give her back her uniform, but she insisted that he had to wear it.

“Futaro while you look like me you are forbidden on wearing anything that I don’t give the okay in. From now on your clothes are not to be worn at all.”

“What this isn’t fair!” Futaro protested, but at the same time, he had already begun to put her uniform on.

“I don’t care if you think it’s fair,” Nino said to him, bringing out a hairbrush. “As long as you look like me, I won’t allow you to look ugly. I take pride in my appearance so that must mean that you should as well. Now come over here I need to do your hair.”

Futaro complied sitting down in front of Nino. While she styled his hair, he couldn’t help but notice that wearing a skirt felt somewhat nice, almost liberating even.

“They're done,” Nino said, proud of herself with what she had down. “While it’s not quite up to my standards just yet, I would say that you are most defiantly more passible to look at than before. We can work on getting the finer points down for later. I do believe that we have some studying to do.”

“You’re right to let’s get started,” Futaro said, trying to distract himself from his current form. He knew that if he dwelled on it long enough the fear that he would soon no longer be a male anymore.

As their study session went on Futaro noticed that while he was still having problems with solving the practice questions before him, Nino was just flying through them with ease. Nino noticed this and thought of something fun.

“Don’t worry Futaro you can copy my answers to see how It’s done,” she said slowly moving her answers into Futaro’s line of view.

Futaro thinking that this was nothing more than an act of goodwill from Nino decided that it couldn’t hurt to copy her answers. She did seem like she knew what she was doing.

Nino gave a small snicker seeing out the smug Futaro was enjoying himself by coping her answers. If he wasn’t affected by whatever sort of magic this was then he would never accept her help like this. Though truth be told this wasn’t going to help him at all. While he may get the right answers now that didn’t mean that he would know how to solve them on his own.

“Haah?! It’s not like I enjoy copying you or anything, idiot!” Futaro yelled at her, noticing that she was smugly watching him. Futaro then stormed off to his room for the rest of the day.

For the next several days Nino would begin training Futaro in her daily beauty routine. At first, Futaro resisted it, but Nino made it clear to him that there was no use in arguing with her about it. Eventually, Futaro became quite submissive to Nino as his transformation progressed further.

While they still did study sessions together it was only that in the name. Nino didn’t need to study that much since she had almost completely taken Futaro’s intelligence. She used this time to make sure that Futaro would become more reliant on copying her answers, making him think that she was helping him.

“Oaky Futaro let’s see how you did his time,” Nino said taking the mock test back from Futaro who was once again trying to measure his own intelligence and how far he has regressed.

“Sorry Futaro, but it looks like you scored a 29 this time, so close to passing. I’m still proud that you tried your best,” she said patting him on the shoulder. “Though I on the other hand score a 91 on my current mock test. It would seem that you need to do some more studying,” she said mocking him.

“Haah?! It’s not like you are that smart because you did well on a few tests! Test scores aren’t everything idiot!” Merely a week before Futaro would have never thought that he could sink so low as to say that test scores aren’t everything.

Nino smiled. Futaro was almost exactly like her, there was just one last little thing before “his” transformation was complete.

“Now, now, Futaro, I understand that you’re frustrated, but that is no reason to give up hope. Just take me for an example, a short while ago I was having a hard as well. I just know that if your keep trying things will get better.

“Shut up you don’t know anything!” Futaro yelled at her running to his room, before crying himself to sleep.

That night Futaro had a terrible nightmare. Summer vacation had ended, and he still remained in his sissy Nino form. Not only that but the intelligence that he worked years to acquire, and grow was still gone. As he was called upon by the teacher to answer a simple question, he told her that he couldn’t do it.

He walked back to his desk like all the other students and even the teacher laughed at him. They were all fed up with his past smug attitude and love that he was now too pathetic to defend himself. Even the other sisters made fun of him.

Futaro woke up with sweat running down his back. Tears were flowing out if his eyes, realizing that nothing was ever going to be the same for him. Everyone would abandon him, everyone but her. He knew that Nino would always be there for him so long as he never angered her, she could protect him.

A few seconds later Futaro made his way over to Nino’s room. Her door was wide open, and she was laying in bed asleep but woke up the moment that she saw him standing in the door wearing nothing but his bra and panties, the same as her.

“Futaro what’s wrong?” she asked him.

“I had a nightmare, could I sleep with you?” Futaro asked her with the cutest face that she had ever seen.

“Of course, you can, come here,” she said making room for him on the bed.

“Thank you,” he said, laying down next to her. Then before he could do anything else she embraced him like a body pillow! “Nino what ar-”

“Shh, it’s alright,” she said. “Just sleep, I promise that you’ll have no more nightmares while you’re embraced in my arms.

Futaro quickly fell asleep after that a deep sleep. When he awoke the next morning, he found himself face to face with Nino who had a smile of pure happiness spread across her face.

“Huh, Nino what’s going on?” Futaro asked, still unaware of what had happened while “he” slept.

“Congratulations Futaro you’re now officially a woman!” Nino said, clapping her hands together.

“Nino, what are you talking about?” Futaro asked, not certain about what she was talking about. “You’re just half asleep go back to bed,” Futaro said dismissing her words as nonsense.

“Oh well I guess that you need some physical proof,” Nino said before ripping the blanket off of Futaro and then dragging “him” to “his” feet. Then before Futaro could protest she dragged “him” over to the full body mirror and pulled “his” panties straight down.

Futaro tried to cover “his” male member but found that it was no longer there. Instead, all that was left was her bright tight gateway into womanhood.

“Eeeeeekkkkkkkkkkkkk!!!”  Futaro screamed in fear, falling to her knees. “This can’t be happening! This can’t be happening!”

Futaro couldn’t hold herself back from crying. The last trace of her old self was now gone. There was nothing left of Futaro except her mind. Wait that’s it! If Futaro takes the same mock test as her at the same time. As long as she could get a higher score than Nino all hope was not lost.

“Nino, I challenge you!” Futaro said, wiping her tears from her face, and at the same time standing up to meet Nino at eye level, not noticing that Nino was too busy looking at her new womanhood to even bother looking in her eyes. “We have to take the same mock test at the same time and whoever gets the higher score will be the winner!”

“Fine I accept your challenge,” Nino said back to her. “I was going to ask that as well since supplemental classes will be starting soon. Though before we have to do that, we have to get ready for the day. Remember before everything else we must always look our best.”

“You’re right,” Futaro said agreeing with her as they made their way into the bathroom where Nino did both of their makeup in the exact same way. As she prepared their outfits, she could stop herself from smiling. She was overjoyed with how submissive Futaro had become to her.

When they were finally dressed and ready to go, they looked like identical twins wearing the same outfit, and hairstyles. Even Nino’s sisters would be able to tell them apart since Futaro had longed since started her journey as a tsundere.

“Okay, so who’s ready to take that mock test?” Nino asked as the two of them made their way to the living room.

“I was born ready,” Futaro said as she started the test. This was the mick test that she had the most experience with. Even if her intelligence wasn’t at its peak right now, she could easily remember all the answers to this test. This test was one that she could pass with her eyes closed.

Or that was at least what she thought at the time.

“No way,” she said to herself in despair. “How can this be? This has to be a joke, right? No, it’s a dream, defiantly a dream.” Futaro had a small breakdown after seeing her test score compared to Nino’s. She managed to get a 100 while she was only able to get a messily 12 on hers.

“It’s alright Futaro, I know that you tried your best,” Nino said trying to comfort her.

“Haah?! This test has to be a trick! It’s not like I got stupid or anything idiot!” Futaro who now understood that there was practically nothing left of her old self just started to vent her anger out at Nino. The pride that she had in her once hard-earned intelligence was now gone.

“You know I have an idea that might help you,” Nino said, who was more than happy with the results of the test. “Since supplemental classes start in a few days you should just take my place and go to them instead. You’re practically identical to me and it’s obvious that you need the extra help. You should take this as an opportunity to grow.”

“Ha-”

“Haah?!” Nino said while glaring straight into Futaro’s eyes with a dark tsundere glare. She knew that she couldn’t disobey her, since it was in her submissive nature. It was best for Futaro to do what she wanted her to do.

“Fine I’ll go, but it’s not like I’m grateful or anything like that, stupid,” Futaro said, agreeing to her idea.

From that day on the hierarchy between Futaro and Nino did a complete 180. Nino was now in control and Futaro was now too submissive to go against her will. To prove this, she made Futaro sleep with her as her body pillow for every night that followed after that, holding her tightly enough so that she couldn’t slip away.

During the next few days before the supplemental classes started Nino made sure that Futaro would do her best to act and behave as she would in public, in order to not ruin her image. Futaro tried to resist at first, but after a few stern glares, she fell into line really quickly.

When the day that supplemental classes began Futaro was finally ready to take her place. When she saw Futaro walk out that day she couldn’t help but smile to see how much she had grown and how much she had regressed.

Futaro on the other hand was ticked off. Why the hell should she have to go to supplemental classes with some idiot kids that couldn’t pass their exams in the first place, it was unfair she wasn’t like these kids. She was just having a bad few weeks, it was nothing to worry about honestly.

Nino overreacted when she decided to make her take her place. These classes were supposed to be for Nino, not her. Futaro didn’t need these classes, or at least that is what she thought.

On the first day of her supplemental classes each student there was required to take a mock test. After she finished the test, she felt terrible, it was the hardest test that she had ever taken. While the teacher graded their tests, the other students were to study for the rest of the day. Once the class had ended, they were all directed to grab their tests as they left. Futaro was the last to grab her test.

“Miss Nino was it?” the teacher said as he handed her back her test. “I heard that you had a tutor, perhaps you should show them the results of your test I’m certain that they will be able to help you far more than I.”

Futaro grabbed the test without looking at what she scored and made her way back home. Only half of the day had gone by, but she felt like it was already time for her to pass out. Were supplemental classes always this stressful? She had never been to one until now, so she didn’t know. Did Nino and the others always have to experience something so draining before he came into their lives?

When she finally got home, she found Nino slacking off and watching tv. She spent to the first half of her day studying while she got to relax. This wasn’t fair!

“Oh, look who’s home,” Nino said to Futaro. “Okay let’s get to studying. Your tutor left me an email and told me that out of today’s mock test. To be honest I’m a bit disappointed, a mere 5 on the test. I expected more from you.”

“What are you talking about?” Futaro said, taking the paper out to see what she cored. She was embarrassed to see that what Nino said was the truth.

“Now no more arguing,” Nino said, taking the test from Futaro and taping it to the whiteboard so that he could always see it. “It’s time to study.”

Nino sat Futaro down and took charge. To be honest she was a much better tutor than Futaro ever was. She effortlessly explained subjects to her and show her easy ways of understanding questions.

Though upon realizing that her teaching methods were flawed Futaro tried to make it harder for Nino to teach her, Nino wasn’t going to let that happen.

“Haah?! Do you really think that you could have done a better job?” she asked Futaro in a dark tone. “If you knew what you were doing you wouldn’t have gotten a 5 on your mock test,” she said pointing to Futaro’s recent mock test.

“Haah?! It’s not like that test was that hard! I just didn’t feel the need to try hard on it. That test was not accurate to my skill level idiot!” Futaro said, trying to deny the fact that she did bad on her test.

“Haah?!” Nino said angrily back to her. “So, if I give you a test that is better for your skill level, you won’t mind what result you get?”

“Yes!” Futaro said in joy, Nino was finally listening to her. “But you have to let me pick the test.”

“Fine, have it your way,” Nino said to Futaro. “But don’t come crying to me when you fail again,” she said handing Futaro a bunch of tests for her to look through.

Once Futaro found the test that she thought she could do the best in she started it as fast as she could. After an hour she was finally done and handed the test back to Nino.

“So, what did I get?” Futaro excitingly asked Nino.

“Um, you got a 53,” Nino said to her. “But Futaro there is something that you shou-”

“Yay!!! I got a 53! I’m still smart!” Futaro was ecstatic by her high score, but because of that, she didn’t listen to what Nino wanted to tell her.

Nino wanted to tell her that the test that Futaro took was for freshmen in junior high school. The fact that she only got a 53 on something that she should have easily gotten a 100 on was quite sad. Though Nino thought that it would be fine to let Futaro believe that she did well on her test.

For the next few weeks, this routine would continue. Futaro would be dressed up by Nino to look cute, she would go to classes in the morning, in the afternoon she would study under Nino, and then at night, she would be used as Nino’s personal body pillow.

While Nino was happy with their current situation she still wanted more. Once Futaro was asleep she made her way back to the shrine where the old lady from over a month before was waiting for her.

“I can tell by the expression on your face that your wish can try,” she said to Nino slowly walking over to her.

“You’re right,” Nino said back to her. I don’t know how exactly it worked, but I granted my wish in the best possible way, but…”

“But you want more,” the old lady said to her. “I can see it in your eyes. There is one last thing that you have planned for that young lad, or should I say, young girl.”

“Yes, please give me another one of those magical charms, I’ll pay you double the amount I gave you before,” she said pulling out a wad of cash. She needed this charm to make just one last wish, one that would change Futaro’s life permanently.

“Oh my, what I firm believer of this shrine you have become and in such a short time as well,” the old lady said, pulling out another charm. “I will accept your payment, but there is one thing that you must promise me before I give you the charm,” the old lady said to her.

“What is it?” Nino asked, anxious to get the charm.

“Just promise to tell your friends, “The old lady said with a sweet smile on her face, before accepting Nino’s money and then handing her the charm.

“Thank you, and I will,” Nino said running back home with the charm in her hands. She was going to make her wish right in front of Futaro.

When she finally made it back home, she found Futaro still asleep on her bed wearing the blue baby doll lingerie that she had given her to compliment her pink baby doll lingerie. Nino’s siblings were coming back from vacation in the morning, and she knew that they would try to stop her if they knew her plan.

“I wish that Futaro was a permanent part of my family.” Her wish was simple and to the point. Upon going to sleep she was excited to see what changes the magic would bring this time.

When Nino woke up the next day, she could tell that the wish had worked. She didn’t know how she knew, but the urge that she had to call Futaro by her new name.

“Oh Mino-chan it’s time to wake up,” Nino said sweetly, stroking Mino’s hair with her hands.

“Huh, Nino onee-chan what’s wrong? Wait why did I just call you onee-chan? Why did you call me Mino? What going on here?” she asked trying to back away from Nino, but since she was still being used as Nino’s body pillow it was impossible for her to escape.

“Isn’t it great? Mino-chan, thanks to the wish I made last night to make you my little sister. From today onwards you have five older sisters! Isn’t it great?”

“What are you talking about?” Mino asked confused by what she was talking about.

“Well it’s similar to the wish that I used on you to turn you into my twin and steal your intelligence,” she said not caring if she knew now since it no longer mattered. Mino couldn’t fight back against her, and she made sure that this entire summer Mino would be submissive to her every demand.

“You did what to me! Onee-chan how could you?!” Mino yelled at her.

“It’s alright Mino-chan,” Nino said in a sweet voice to calm her down. In exchange for that disgusting male form of yours and your intelligence, you gained yourself this adorable new body of yours and sisters that will pamper you to no end. Isn’t that great Mino-chan?

“Well, I guess having sisters would be nice,” Mino said.

“OMG! Mino-chan is blushing!” Nino said with joy. I knew that she would like the new name that I picked out for her. She’s such a good little sister.”

“Haah?! It’s not like I enjoy being called Mino or anything idiot!” Mino yelled at her trying to hide her embarrassment.

“Aww, you’re such a little cutie,” Nino said, embracing Mino tightly in her arms.

“Ugh, let go of me onee-chan, and change me back!” Mino complained. “You did this to me so that means that you can turn me back!”

“Haah?! And why would I do that my cute little sister? I like you this way, and I’m sure that the others would too if they could recognize that you weren’t originally our sister, but my wish rewrote reality. Futaro Uesugi never existed, you nothing more than Mino Nakano, the youngest of the sextuplets. Now get changed the others will be home soon and I’m sure that they’re dying to see you again.

“Yes onee-chan,” Mino said listening to Nino. While she was technically still Futaro on the inside, her personality combined with Nino’s tsundere personality had long since rewritten how she acted. She was no longer the smug and intelligent Futaro that she remembered she was. Perhaps Nino onee-chan was right. Perhaps she was better off as their new little sister.

“That’s a good girl now, let’s get ready Mino-chan,” Nino said as they both got out of bed together.

As Nino and Mino got dressed Mino made sure to copy Nino’s exact movements. Nino was someone that Mino had to look up to. If she did then she could be as perfect as her. During these several weeks with her, she has learned that Nino isn’t the slacker that she thought she was. Nino put one hundred percent effort into everything she did.

She knew that no matter how hard she studied or paid attention in class that she would never be able to go back to being Futaro. The best thing for her to do is to continue with her newfound obsession with Nino onee-chan, besides watching her was much more interesting than studying.

When they were done getting ready, they looked identical to each other. The only difference was that Nino made Mino wear teddy bear hair ties to show that she was the baby bear of the family.

“Nino, Mino, we’re back!” Their sisters yelled as they came inside.

Nino and Mino came to see them a few seconds later.

“So how was your trip?” Nino asked them, giving each one of them a hug.

“It was amazing,” Miku said.

“You should have been with us,” said Ichika.

“She would have been if someone had passed their exams in the first place,” Yotsuba said, looking straight at Mino. “And they call me the dumb one.”

“She did have to stay behind just to tutor her,” said Ichika.

“Well, she does have the best grades among all of us by a large margin,” said Miku. “It’s no wonder that dad asked her to stay behind and keep an eye on our troublesome little sister.”

“Now, now, everyone don’t be mean, Mino tries her best,” said Itsuki. She’ll get better eventually, but not if we keep making fun of her like this. Look she’s even hiding behind Nino now because you guys upset her. It’s okay Mino I promise that we won’t make fun of you.”

“Haah?! Do you really think that your words could hurt me?” she said as small tears began to form in her eyes.

“It’s alright Mino they didn’t mean it,” Nino said comforting her.

“Mino we’re sorry!” they all said at once.

“Look we brought you guys some souvenirs,” Ichika said, showing them the bags that they had brought back with them.

“You didn’t have to,” Mino said to them, trying to hide the fact that she was happy that her sisters cared for her this much and thought of her while they were off having fun.

“We brought you guys some exotic chocolate to eat. It was so delicious that we had dad buy us ten boxes of it,” said Yotsuba.

“There are even some new clothes for you girls from some of the designer stores that we went to,” said Miku.

“And last but not least because there are still a few days before summer is officially over, we got you girls new swimsuits, for when we go to the beach,” said Itsuki. “And yes, Mino before you ask, we got you and Nino the same swimsuit, the only difference is that hers is black and yours is white.”

“Haah?! It’s not like I want to look like Nino onee-chan all the time idiots!” Mino yelled at them trying to hide just how happy she was to be able to look like Nino.

“Classic Mino,” said Miku.

“Just as you would expect from her,” said Itsuki.

“What a sis-con,” said Ichika.

“What a tsundere,” said Yotsuba.

“What a little cutie,” said Nino.

“But she’s our sister so we accept her as she is,” they all said together.

“Haah?! It’s not like I’m happy to be your sister or anything idiots!” Mino yelled in embarrassment. Hopefully, she enjoys her new life, because this was only the beginning.

AFTERWORDS:

“The beach is so lovely,” Miku said, as she and her sister sisters began to set up their spot on the beach.

“Okay girls, you know the drill,” said Itsuki said. “Everyone needs suntan lotion. Divide up into pairs.”

When everyone paired up Mino was paired with Nino because she was too distracted. While her new swimsuit looked amazing and she loved how it matched Nino’s, she couldn’t help feeling that there were multiple gazes on her.

“Come on Mino what are you waiting for?” Nino asked already laying chest first on the beach towel with the strings of her bikini taken off so that Mino could do her back.

“Now I trust that you won’t don’t anything too perverted,” Nino said to Mino.

“Haah?! Why would I want to do that to you, idiot! It’s not that I think you’re the most beautiful girl in the world or anything!” Nino said, flustered by the sight of her sister's bare back.

“Uuugh, aaaahhh,” Mino careful, your not doing it right,” Nino said, able to hold back her moans of pleasure. While this may have been Mino’s first-time applying suntan lotion to another girl, she was a prove at it, but she wasn’t going to admit it to her face.

The rest of the girls had long since applied their suntan lotion on each other and were watching in awe at Mino’s technique and Nino’s refusal to give in.

“Okay it’s my turn,” Nino said, pushing Mino onto the towel and then uniting the string to her bikini top.

“Wait onee-chan I’m not rea- aaaaaaah! Oh my god, it aaah, so goo-” Mino say that her sisters were watching her with an intense gaze, waiting to see how Mino would react.

“Haaaaahh?! Do you aahh, really think that I ahhhn, would like being touch by, ugh, onee-chan idoi-aaaaaaaaaaah!” Mino could hold her moans back as Nino began to apply lotion to her more sensitive places.

When she was finally done applying the suntan lotion Mino was laying on the beach towel with a bright red face filled with embarrassment.

“Mino’s way too much of a sis-con, where do you think it comes from?” Yotsuba asked.

“It doesn’t matter,” everyone else said. “Mino-chan is are little sister and that means that we will spoil her regardless of her quirks.”
